IMPROVEMENT IN CATTLE GUARD GATE.

TO ALL WHOM IT MAY oon'onnm Be it known that I, ARMSTRONG FREEMAN, ofLowelhin the county of Kent, and State of Michigan, have inventedcertain 'new and useful Improvements in Cattle Guard Gates; and I dohereby declare that the following is a full and complete description ofthe same, reference being had to the accompanying drawings, making partof this specification, in which-- 7 Figure 1 is a side view of the gateextended.

Figure 2 is a top view.

Figure 3, an end view of the same.

Like letters of reference refer to like parts in the diflerent views.

A, fig. 1, is the gate, which consists of a number of slots, B, arrangedand pivoted together at the points X, as shown in fig. 1, thus making anextensive and contractive gate which is operated as and for the purposehereafter shown. This gate is pivoted a distance above the ground to apost, 0, at the point a, andisfurthermore supported upon a groovedwheel, D, traversing a rail, E, (fig. FF (fig. 2) are railroad ties, onwhich are laid the rails G G. Along the outer side of rail G is a rail,H, secured upon the ends ofthe levers I, (fig. 1,) said levers beingpivoted to the stays J, upon which they vibrate, thereby allowing therail G to be raised upward and'downward, as will hereafter be described.Projecting at right angles from the top of the levers are standards If,(fig. 1,) shorcd by the braces K. The upper ends of these standards areconnected to levers K by chains L. Said levers K are pivoted to the topof the standards or posts L, (fig. 3,) and have a horizontal movement,theirfrce ends crossing each other at the rear end of the gate, andagainst which they are drawn for a purpose hereafter shown. M (fig.1)'is a short post, to which is pivoted a standard, M. The upper cud ofthis standard is connected to the gate by links N. Projecting back fromthis standard is an arm, N, to which is attached a weight, 0, wherebythe gate is closed after being opened by the passing train. On the trainpassing over the section of the road exhibited in the drawing, thewheels strike upon and prcssdown the side or movable rail H level to thetread of the line rail G, the effect of which is todraw the end of thestandard J in the direction of the dotted line a. This being connectedto the levers K, draws the free end of them against, the rear end of thegate, which causes it to draw up and back from its position across thetrack in virtue of the leverage exerted upon the slats composing thegate; the gate in construction being a succession of simple leversexerting their powerupon each other from the fulcrum a to the front'endof the gate. As the gate contracts, the arm N and weight rise up indirection of the dotted line b. Thegate by this means is drawn fromacross the track, leaving it clear for the train to pass, which onhaving passed, and the weight of the last car rolled from oil' the siderail H, the weight 0 suspended from the arm N, and the weight 0 on theend of the lover I, exerted upon the slat directly pivoted to the postC, and which is the first lever throughwhich all the others are moved,causes an extension of the gate across the track, as shown in fig. 1,thereby shutting out cattle and other animals from the road; and so on,alternately, as the coming train rolls on to the rails G G', andpressing down the side rail H, the gate gathers back from off the roadby the action ofthc levers K exerted against the rear end of the gate,as above described, and again extended by the weights 0 O. In order tofacilitate the movement of the gate, and prevent any undue strain andsagging, thc roller D, above referred to, is attached to the bottom ofthe gate, and upon which it rolls easily, and without restraint. Theholes through which 'the pivots are inserted in the construction of thegate, arebushcd with iron or any other suitable material, therebyreducing the friction and wearing of the gate, thus rendering it mucheasier in its operation, and more durable.

What I claim as my improvement, and desire to secure by Letters Patent,is

1. The side rail H, lever I, chains L, and levers K, as arranged, .incombination with the gate A, for the purpose and in the manner as setforth.

2.-The gate A, and roller D, as arranged, in combination with thestandard M, links N, and weighted arm N, in the manner and for thepurpose herein described.

ARMSTRONG FREEMAN.
